Below are all our prices and ordering information for our conversion
kits, cylinders, and parts. Do not ask us which kit or cylinders
to order. Read the information as only one kit is the proper kit
for your engine. Measure your vehicle then read the cylinder
dimensions and then you decide which cylinder meets your
needs. You may want more than one cylinder to increase your
driving range. All the cylinders we have available are listed
here on this page, so do not ask us if we have larger or smaller
cylinders.
Please read all our pages before
ordering or asking questions!
All our prices and Cylinder Specifications are on this page.
All our mixer
kits for EFI engines use all the same parts except the size of the
mixer and fuel injector parts.
We are telling you this as we get many people asking if we have a kit
that will work on their engine.
The answer is always yes, so please do
not call or email to ask. See our FAQ page for details on hybrids.
If you need to use the kit on another same size engine you do not need
any new parts. If installed on a larger or smaller engine you may
need a new mixer, or injector controller and wire harness parts.
Our diesel kit does not use a mixer or injector parts so the same kit
works on all diesel engines of any size.
You provide us with the information
requested below and we provide the correct parts for your engine.
We have been selling kits since 2008 and have sold kits for nearly
every engine.
We are the largest seller of mixer kits in the USA.
Call to order 801-825-5580 or FAX to 801-825-5428. We accept all 4 major credit cards.

Conversion
Kit
These kits are low cost
and easy to
install. This kit is available for all gasoline engines including all EFI throttle body or multiport, carburetor, and even turbo or super charged engines. This is how it works: A mixer (venturi) is installed in the air intake before the throttle body which provides single point fuel injection. An oxygen sensor on the engine's exhaust is monitored by the CNG controller which controls an electronic valve (stepper motor) installed on the low pressure CNG fuel hose going to the mixer to provide the proper fuel ratio at all times. On all gasoline engines the combustion air has always been controlled with a throttle plate so it makes sense to bring the fuel in with the air letting the oxygen sensor adjust the fuel ratio. This provides the best mixing of the gas and air which provides excellent engine performance. The engine idles and runs the same as it does on gasoline without the intense programming and adjusting needed with sequential injection conversion kits. There is more information on sequential kits above. The mixer does restrict the air flow some when running on gasoline, but not enough to effect the performance or fuel economy. The instructions are written for the car owner to install with many tips, "how to" information and a trouble guide. No programming is needed as we have each controller programmed for your engines requirements. Computer cable and software is available if desired. All you have to do is adjust the idle screw on the regulator and observe the indicator lights that let you know it is adjusted properly. Our controller features self adjusting electronics which always provides peak performance. The control on the dash indicates which fuel you are using and how much CNG is in your cylinder. This kit allows you to run on either gasoline or CNG with the push of a button on the dash. Our kits for 8 or 10 cylinder engines come with high output regulators for more power and better performance. You can upgrade your smaller engine kit to a high output regulator for an additional fee. If you run out of CNG you will begin to loose power so you just push the button on the dash and you will switch to gasoline and continue driving. You should always refuel before you run out of either fuel. Read the features of both our EWS and Millennium kits to decide which kit you would prefer. |

Similar to picture above. New picture coming soon. Diesel Kit This is a duel fuel kit so the engine runs on both diesel and CNG at the same time. This kit will provide the engine with more power because of the high octane of CNG and the high compression of a diesel engine. The regulator is easily adjusted with the idle screw on the regulator so you get little or no CNG while at an idle. As you accelerate the engine will suck CNG from the regulator and into the air intake. The more throttle the more CNG. You will use less diesel as you will use less throttle. You will get about 25% more power. Most engines will use about 60% CNG and 40% diesel, and with no other adjustments needed. The combined fuel usage is about the same as using only diesel. The cost savings are not as great as with a gasoline engine because you are still using some diesel. The instructions are written for the car owner to install with many tips, and "how to" information. No programming of the controller is needed with this kit. The CNG is fed into the air intake hose before the turbo. A mixer is not needed. The control on the dash lets you know if the CNG is being used and how much CNG is in the cylinder. You can turn the CNG off or on with the push of a button on the dash. If you run out of CNG you will loose the power gained using CNG and continue just running on diesel. Warning Beware of expensive Diesel Conversion Kits that can run on a high percentage of CNG as these kits can damage your engine or exhaust. Our kits are safe and will not damage your engine or exhaust when installed and adjusted properly. We have sold hundreds of this kit with no damage to any engine or exhaust system. |
